To track the quality of instruction delivered at the University of Western Australia, the university surveys all units using its Students’ Unit Reflective Feedback (SURF) metrics, and faculties use these metrics to benchmark student satisfaction. Consequently, teaching staff are actively encouraged to adopt teaching practices that will increase the average levels of these metrics. Using a ‘before-after’ approach, we compared these metrics before and after the implementation of improved teaching practices that addressed specific weaknesses identified through student responses for two undergraduate units. Despite the implementation of improved teaching practices, SURF scores did not increase significantly for the two units assessed, due possibly to the components of the academic programme covered by the SURF questions, the field-based nature of the units, and the difficulty in measuring an increase in the SURF scores of units which already score highly. This poor sensitivity of the SURF metrics to the implementation of improved teaching practices could have implications for their use for performance assessment by the university. 相似文献

Florida and Puerto Rico Secondary Science Teachers’ Knowledge and Teaching of Climate Change Science
Benjamin C. Herman Allan Feldman Vanessa Vernaza-Hernandez 《International Journal of Science and Mathematics Education》2017,15(3):451-471
Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation. 相似文献

Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables. 相似文献

Drawing on Noddings’ work on religion and education (1993), moral education (2002), and citizenship education (2005\, 2015), this article contemplates how educators both in public schools and parochial Jewish schools might teach students to care about critical issues confronting the Jewish community historically and contemporarily. Its premise is that the teaching of the Jewish experience is presently deficient in both school settings. The article suggests ways that Noddings’ conceptions of caring (1992), pedagogical neutrality (1993), and critical lessons (2006) can be adapted and applied to the teaching of Jewish civilization in more appropriate, holistic, and nuanced ways. Its implications are applicable to many other American subgroups whose treatment in the social studies curriculum is typically inadequate. 相似文献

(Trans)lating Identity: Exploring Discursive Strategies for Navigating the Tensions of Identity Gaps
This study explored the formation and expression of gender identity among 19 self-identified transgender individuals through the use of qualitative, in-depth interviews. Through the lens of the Communication Theory of Identity (CTI), we examined how trans* individuals form and perform gender identity, the tensions produced between identity frames, and the discursive strategies used to navigate those tensions. We identified the manifestation of three specific identity gaps: personal-enacted, personal-relational, and enacted-relational. Furthermore, we discovered four discursive strategies previously recognized for navigating tensions that emerge from identity gaps: closeted enactment, passing, disengagement, and label changing, and we identified a fifth discursive strategy—hyper-engagement—used to navigate these tensions. Results revealed that these identity layers and discursive strategies collaboratively manifest and coalesce in response to specific communicative contexts. Our results are discussed within the resounding call for greater understanding of trans* identity formation and expression. 相似文献

In two studies, we investigated how learning strategies can support learning from multimedia. In the first study, 112 students learned from a web-based learning environment. On the basis of a strategy, one group of students took typewritten notes. The second group of students wrote a summary. Producing typewritten notes did not benefit learning any more than writing a summary. In the second study, 100 students learned the same subject matter from print. On the basis of a strategy, the first group produced written notes, the second group highlighted, wrote notes, and produced sketches. The third group wrote a summary. The students who highlighted, wrote notes, and produced sketches outperformed the other students. The students who produced written notes only did not learn more successfully than those who wrote a summary. The results suggest that externalizations in general and sketches in particular may play an important role in multimedia learning. 相似文献

The bioactivity of the aqueous extracts of the leaf and stem bark of the medicinal plant, Alstonia boonei De Wild (Apocyanaceae), against the pink stalk borer, Sesamia calamistis Hampson (Lepidoptera: Noctuidae) was studied in a laboratory bioassay. The extracts were incorporated into artificial diet at a rate of 0.0% (control), 1.0%, 2.5%, 5.0%, and 10.0% (w/w). Both extracts significantly (P<0.01) reduced larval survival and weight in a dose dependent manner. The concentrations that killed 50% of the larvae (LC50) for the stem bark extract were 2.8% and 2.1% at 10 and 20 DAI (days after introduction), respectively, while those for the leaves extract were 5.6% and 3.5%. The weights of the larvae also varied significantly (P<0.05) between the treatments in a dose dependent manner. We conclude that both leaf and stem bark extracts of A. boonei are toxic, used as growth inhibitors to S. calamistis larvae, and hold good promise for use as alternative crop protectants against S. calamistis. 相似文献
